IMD forecasts heavy rain in some West Bengal districts till Aug 10
Kolkata, Aug 5 (PTI) The IMD on Monday forecast heavy rain in some districts of West Bengal till August 10, owing to an upper air circulation over north Bangladesh and an active monsoon trough.
Heavy rainfall is likely at one or two places in the sub-Himalayan districts of Darjeeling, Kalimpong, Jalpaiguri, Cooch Behar and Alipurduar till August 10, the India Meteorological Department said in a bulletin.
The south Bengal districts of North and South 24 Parganas, Howrah, Bankura and Purulia are also expected to receive heavy rain till the morning of August 8, it said.
Light to moderate rain will occur in all the other districts of West Bengal, the IMD said in its forecast till August 10.
Barrackpore in North 24 Parganas district recorded the highest rainfall in West Bengal in the past 24 hours till 8.30 am on Tuesday at 48 mm. Kolkata recorded 42-mm rainfall during the period, it said.

Constructions added to climate crisis woes
The series of suspected cloudbursts that hit three locations near Harsil, a village between Uttarkashi and Gagotri in Uttarakhand, was triggered by the monsoon trough being more north than it usually is at this time of the year, and accentuated by a cyclonic system over Bihar. according to experts. Glaciers are melting and the debris from the glaciers are flowing with the river water. (PTI photo) According to Uttarkashi district administration, at least 20 people are missing and about 80-90 buildings have been damaged as a result of the extreme weather events, likely caused by the climate crisis, and exacerbated by untrammelled construction in the region, including in river beds and on fragile slopes. A status note on Tuesday evening by the Central Water Commission said a series of extreme weather events in the form of suspected cloudbursts occurred in quick succession on Tuesday in the Uttarkashi district, causing widespread damage and potential casualties. The first incident took place in Dharali, near Harshil, around 1:00 pm. The second incident occurred between Harshil and Gangnani (near Sukki Top), around 3:00 pm. And the third incident occurred near Army Camp, Harshil, around 3:30 pm Horrifying videos of multiple buildings, habitations, market areas being washed away in the Bhagirathi Ecosensitive Zone, has once again captured the impact of climate change in the upper reaches of the Western Himalayas. But the experts also said that the impact has been particularly devastating because of the number of constructions on what appears to be the riverbed of Khir Ganga, a tributary of Bhagirathi. Heavy rain, or cloudburst? India Meteorological Department officials said there was no way to confirm if the extreme weather events were 'cloudbursts'. Cloudbursts are very localised phenomena that result in rain of 100mm in an hour. 'There has been extremely heavy rainfall, over 300 mm in parts of Uttarakhand in the past 24 hours. As you can see from the video, extremely heavy rain may have occurred in very high reaches. We have no way to monitor if it was in fact a cloudburst as there are no stations in very high altitude areas. But we know that there was extremely heavy rain,' said M Mohapatra, director general, IMD. 'The monsoon trough has been to the north of its normal position for the past three days causing concentrated, heavy rain only over the Himalayan foothills. When such continued rainfall occurs, in certain areas the soil saturates and water overflows. The water is seen flowing downstream. There is also a cyclonic circulation over Bihar and surrounding regions, accentuating the impact,' he added. The frequency of such events has been increasing. There has been a rise in short span high intensity rain occurrences (mini cloudbursts) along the west coast of India and along the foothills of Western Himalayas between 1969 and 2015 according to 'Assessment of Climate Change over the Indian Region,' a report by the union ministry of earth sciences published in 2020. 'There is clear evidence that extreme precipitation has increased everywhere including these hilly states. This is a clear signal of global warming. This heavy rain and flash flood is not unexpected. The number of cloudbursts is most certainly going up in the hilly states,' said M Rajeevan, former secretary, ministry of earth sciences and climate scientist. Scientists have also said even if heavy rainfall events do not meet the exact criteria defined, but cause extensive damage such as flash floods and landslides in high altitude areas, they should also be considered cloudbursts. 'The Himalayan region is experiencing higher warming than the global mean. This is known as elevated warming. This can increase cloudbursts, as under warm condition water holding capacity of air increases and strong upward movement of air due to slope increases moisture in the air leads to a cloudburst in mountainous terrain,' said Anil Kulkarni, distinguished visiting scientist, Divecha Center for Climate Change, Indian Institute of Science. 'Since 2018 we are seeing a major escalation in extreme weather events and associated disasters. Even before the Kedarnath disaster in 2013, there were two major cloudbursts in Assi Ganga and Ukhimath. But after 2018 we saw a huge spike in landslides in all the valleys. In 2021 there was the Rishi Ganga disaster in which 200 workers were killed in the tunnel after the glacier fell apart. Then there was the Joshimath land sinking, the Silkayara tunnel and major rain disaster in Yamuna valley this monsoon. It is relentless. We are 100% sure that cloudburst frequency has gone up. The impact of cloudburst is also much more devastating now because of the amount of debris involved. Glaciers are melting and the debris from the glaciers are flowing with the river water. This is causing extensive damage every time,'said Mallika Bhanot, environmentalist and member of Ganga Ahvaan, a civil society collective. But there are man made factors making things worse 'Increased development activity in vulnerable regions creates new risks to the mountain community,' said Kulkarni. Indeed, it is important to recognize that the increase in such events in Uttarakhand is not exclusively because of the climate crisis, added Bhaot. ' You can see the anthropogenic signature in every such disaster. In the videos we can see hotels, big buildings right on the river bed. The river will take its route. It is only natural to expect that it will flow freely. Any hindrances to its flow will obviously cause disasters. The massive increase in the number of landslides is again completely linked to road construction on the Char Dham route,' added Bhanot. The government has pushed through this project citing security concerns -- it goes right up to the India-China border -- but there is no denying that it has increased the fragility of already vulnerable hills. NDMA scientists have not ruled out glacier breach/avalanche event: 'We have received a status report from the Ministry of Jal Shakti which says that a suspected cloudburst is likely to have triggered the disasters. IMD had also issued an orange alert for Uttarkashi. We are assessing three probable scenarios. One, there was a cloudburst in the catchment of Khir Ganga. Second, there was prolonged rainfall in the upper reaches of Western Himalayas that saturated the soil and water could not percolate any further. Third, there are 13 large glacial lakes in Uttarakhand and this may be an ice-rock avalanche from one of those lakes. This needs deeper analysis. We will also check if infrastructure played a role in the post disaster assessment depending on the need,' said Dipali Jindal, senior consultant, National Disaster Management Authority. 'These kind of rainfall events were rare and take place once in 20 or 50 years. However nowadays such events are becoming frequent due to climate change. Such mudslide normally happens when there is very heavy rain upstream. In the videos, we can see dense settlements near the river bank. These come in the right of way of the river. We should have a safe zone for buildings, hotels, habitations. Zonation is v important in such regions,' said Manish Shrestha, Hydrologist, International Centre for Integrated Mountain Development (ICIMOD).

Explained: What's causing relentless rain in Uttarakhand, Himachal, J&K, UP
Several northern states, including Uttarakhand, Himachal Pradesh, Jammu and Kashmir, and parts of Uttar Pradesh, are witnessing unusually heavy rainfall — a direct consequence of interacting weather systems within the monsoon the heart of the ongoing downpour is the monsoon trough, a low-pressure belt that currently runs close to the Himalayan foothills. This trough acts as a convergence zone, drawing in moisture-laden winds from both the Arabian Sea and the Bay of Bengal. As these moist winds meet and rise, they condense to form extensive cloud cover, triggering widespread amplifying the situation further is the presence of an upper-level Western Disturbance (WD), a weather system originating in the Mediterranean that moves eastward over northern India. These disturbances typically bring cooler air and added moisture. When a WD interacts with the monsoon trough, it enhances vertical air movement, particularly due to divergence at higher altitudes. This upper-level divergence allows air to rise more rapidly from the surface, encouraging cloud formation and heavy precipitation. In technical terms, this is a classic case of enhanced convection — where warm, moist air is lifted swiftly into the upper atmosphere, where it cools, condenses, and releases intense combined effect of the monsoon trough at the surface and the upper-level WD has created a weather pattern conducive to persistent, widespread, and intense rain across the Himalayan belt and adjoining plains. This meteorological setup not only increases rainfall totals but also raises the risk of flooding, landslides, and other rain-related hazards, particularly in vulnerable hill are closely monitoring the evolving conditions as the heavy spell continues to batter several parts of North India.- EndsMust Watch

Weather today: IMD alerts for Uttarakhand day after cloudburst, flash flood; Delhi remains dry
The India Meteorological Department (IMD) has issued heavy rainfall warnings across India, including Uttarakhand, Himachal Pradesh, Kerala, Tamil Nadu, West Bengal, and Arunachal Pradesh. Meanwhile, the national capital Delhi remains dry, with temperatures expected to soar. On August 5, cloudburst-triggered flash floods and mud slides in Uttarakhand's Uttarkashi district caused severe damage to homes, shops and roads, and has resulted in several people feared missing, according to an ANI report. More than 130 people have been rescued so far from devastation caused by two cloudbursts, one in Dharali and another in the Sukhi Top area, Uttarakhand government officials said. Efforts led by the Indian Army, Indo-Tibetan Border Police (ITBP), National Disaster Response Force (NDRF), and State Disaster Response Force (SDRF), are ongoing. The Met Department has issued warnings for heavy rainfall across the state today, especially in the hill districts. Meanwhile, in the Malappuram district of Kerala, heavy rainfall has caused waterlogging across the region, with the state's ghats receiving five-day 'very heavy rainfall' forecast from the IMD, as per another ANI report. Further, the neighbouring southern state of Tamil Nadu has also got a 'very heavy rainfall' warning from the IMD for the same period, it added. Himachal Pradesh has recieved heavy rainfall over the past six consecutive days, affecting daily life across the region. Many areas have been affected by dense fog, landslides and waterlogging. The IMD has issued an orange alert for heavy rainfall in several districts, including Shimla, Solan, Mandi, Bilaspur, Una, Hamirpur, and Kangra, ANI reported. The national capital Delhi saw maximum temperature at 32.7 degrees Celsius on August 5, a notch below the season's average, while the minimum was recorded at 25.8 degrees Celsius, one degree below normal, as per the weather department, And while no rainfall was recorded over the past 24 hours, humidity levels remained high, oscillating between 75 per cent in the morning and 69 per cent in the evening. On August 6, IMD has forecast thunderstorms with rain, with minimum and maximum temperatures likely to hover around 25 and 34 degrees Celsius, respectively. The IMD has forecast heavy rain in some districts of West Bengal till August 10, owing to an upper air circulation over north Bangladesh and an active monsoon trough, PTI reported. The bulletin noted heavy rainfall is likely in Darjeeling, Kalimpong, Jalpaiguri, Cooch Behar and Alipurduar till August 10; with heavy rains expected in North and South 24 Parganas, Howrah, Bankura and Purulia till August 8. Meanwhile a prediction of 'light to moderate rain' has been issued for all other districts of West Bengal till August 10; and thunderstorms with lightning in Kolkata till August 8. On August 6, an IMD yellow alert remains in effect for several districts in Arunachal Pradesh due to anticipated thunderstorms and moderate to heavy showers, including East Kameng, Namsai, Lohit, and Papum Pare, PTI reported. The Met has issued a series of weather alerts for the next five days amid forecast for rain and thunderstorms across districts, with East Kameng also likely to experience hail, while heavy showers have been predicted over West Kameng and Upper Subansiri. Most other districts, including Siang, Kurung Kumey, and Tawang, are expected to receive scattered rain and thunderstorms with a high probability of occurrence. Fairly widespread rainfall is forecasted for Namsai, West Siang, and East Kameng. (With inputs from ANI, PTI)
